Many thanks, that makes a lot of sense. I filtered the solution right after your post, and will use deionized water in the future. Any idea why this never happend with Kodak's or Ilford's WashAid?
I could be wrong, but I have read somewhere that Kodak included in some of their formulas chemicals to deal with the impurities in domestic water. Somebody else will have to confirm this (or refute it).
